'To aZ-Z whom it may concern:

Be it known that 1, PARVIN WRIGHT, a citizen of the United States, residing at Chicago, inthe county of Cook and State of Illinois, have invented'certain new and useful Improvements in Tie Wi'rejor Fabric Rolls; and l do hereby declare the following to be a full, clear, and exact description of-the invention, such as will enable Others skilled in the art to which it appertains to make and use the same.

This invention relates to tie wires for tabric rolls and similar articles and has for its object to provide a tie wire which is more simple in construction and more eificient in operation than those heretofore proposed With these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

This application constitutes a conti uation of my co-pending application Seria' No. 7 16,17 8, filed May 27, 19241, and entitled Wire knot forming tool.

Figure 14 is a sectional view taken on the line 14l14 of Figure 13 and looking in the direction of the arrows.

In the drawings the tie wire is shown as comprising a straight main body portion 1, one end 2 of which lies wholly within said main body portion but the other end 3 of which is formed in any suitable way into a knotted head. These ties are formed,

preferably from coiled wire running through suitable straightening mechanism and cut off into predetermined lengths,

which lengths are then operated upon by mechanism such as disclosed in my copending application filed July 12, 1924, Serial til the loop 5. The main body portion 1 of the tie as will be clearly seen from the drawings is wrapped around the extreme end portion 6 to form a second loop 10 which lies in a plane intersecting the plane of the lltltl first loop 5 and the extreme end portion, 6.

That is to say, the loop 5 may be said to be substantially disposed in a plane substantially at right angles to the main body portion 1 of the tie. Also the loop 5 is provided with an extreme end portion extending from said loop 5 to the other side of said'main body portion and disposed in a plane making a greater angle with said main body portion than the plane of the loop 5. And finally loop 10 is disposed in a plane intersecting the plane of loop 5 and the plane of the end portion 6.

With particular reference to Figures 2 and 4 it will be noted that the loop 10 is formed with a greater internal diameter than the diameter of the tie wire itself. Further, it will be noted that the portion of the tie wire constituting the extreme freev end 6 contacts with the outer wall 12 of the loop 10 as clearly shown at 13 in Figure 4. Also it is to be observed that the portion 6 by contacting with the outer wall 12 of said loop provides the space 15 between said portion 6 and the inner wall 16 of the loop 10. The purpose of this arrangement of parts will be disclosed later. I

When it is desired to apply such a tie wire as that shown in Figure 1 to a roll of fabric 20, see Figure 6, the straight end portion 2 of said tie is passed through the apertured head 21 provided at one end of that the said portion 2' of the tie will be engaged in the groove 31 of the tool. The

I handle 33 is then rotated about its shank portion 34 as an axis as indicated by the arrows in Figure 6 whereupon the groove 1 '31 and the wire lying thereinwill be drawn continuation.

When the parts are in such a position as shown in Figure 7 the handle 33 and its shank 34 are then rotated in the direction of the arrows in said figure about the axis ofthe cylinder 35 whereupon as shown in Fi re 8 the extreme-end portion 2 of.the tie will have been turned over to a contacting position relative to the main body portion 1 of said tie. As a result of the operations shown in Figures 6, 7 and 8 it will be seen that there has been provided in the straight end of the tie, a U-shaped loop 40 having its extreme free end portion 2 ex-.

tending beyond and substantially at right angles to the main body portion 1 of the tie.

The next operation is illustrated in Figure 9 wherein it will be seen that the handle 33 is rotated in the direction of the arrows about its shank portion 34: as an axis so as to propel the groove 31, and the loop 40 formed thereon, out of the cylinder 35 Nhen the parts are in the position shown in said Figure 9 the entire tool is then revolved about the axis of the cylinder 35 as a center by turning the handle in the direction of the arrows shown in Figure 10, whereupon as will be clear from the drawings the main" body portion 1 will be wrapped around the extreme free end portion 2 of the tie, forming the knot 43. When the parts are in the position shown. in Figure 10 the hand knot forming tool 30 may then he slipped from the tie as indicated in Figure 12 thus leaving the package 20 secured by the tie wire provided with the knot 3 at one end .and the newly formed knot 43 at the other end.

In the forming of the knot t3 the tie 1 is placed under tension. That is to say, in the forming of the loop 40 and as a result of the operation performed upon the tie and shown in Figure 7, the extreme end of the cylinder 35 will have been drawn into closecontact with the head 22 of the pack-- age, while at the same time the preformed knot 3 at, the other extremity of the tie. is in close contact with the head 21 of said package. Upon the further and successive steps by which the hand tool 30 forms the second knot 43, the tie 1 has a strain placed thereon and in the direction indicated by the arrow in Figure 11. The result of this strain is that the inner wall 16 of the loop 10 is brought in contact with the head 21 of the package as clearly shown in Figures 11 and 12, and the main body portion 1 of the tie is pulled in a direction indicated by the arrows in said figures. The inner wall 16 of the loop 10 is not capable of yielding materially and therefore the result is that the outer wall 12 of said loop-1O is moved from the position indicated in dotted lines in Figure 11 to the position shown in full lines in said figure. Tn thus 'moving the outer wall 12 contacting with the extreme end portion 6 of the knot3, said extreme end portion 6 will likewise be moved from its dotted line position to a positionshown in full lines in said figure 11, while at the same time the space 15 shown in Figure twill become materially less due to the fact that the main body portion 1 iswrapped tighter exists at the end 2 of the tie wire when the second knot 43 is formed therein as by-the hand tool 30. That is to say, the tension of'the tie wire 1 having moved the parts 6 and 12 to the limit. of their movement as shown in Figure 11 and to a slight extent the head 21 of the package, the forming of the knot 43 will form a tension in itself at the opposite end of the package. In other words, as the hand tool is turned about the axis of its cylinder to such a position as shown in Figure 10, the loop of the knot 43 will have been turned so as to wrap the main body portion 1 about the free extending portion 2 of the tie. In fact such a leverage is obtained that considerable pressure is placed on said knot 43. Also inasmuch as the tie wire 1 is formed from tough steel wire, there is an inherent springiness in said wire. The effect of this inherent springiness coupled with the pres-.

in a tight manner not hitherto capab e of.

accomplishment in so far as can be ascertained. That is to say, in the securing means heretofore proposed, said means have not been capable of being subjected to sufficient pressure or spring action to hold the two ends of the package in as tight and secure position as is the case with this invention. It therefore results that packages secured with the tie of this invention are found to be free from damage after shipment due to loose ends of the ties employed.

With the use of the tie disclosed herein, a head 22 is used having a small aperture therein of suflicient size toaccommodate the main body portion 1 only of the tie. 1 That is to say, the head 22 is providedwith a circularly formed aperture 50 of a diameter to allow the main body portion 1 of the tie to closely but slidingly' fitftherein. If necessary, as for heavy packages requiring extra tensioning, the rim'of the aperture 50 may be strengthened by any suitable reinforcement such for example as the ridge 51, see Figures 13 and 14,- upset or pressed from the plane of the head 22.

In the slightly modified form of the inven- I tion shown in Figure 11 the construction is the same as shown in Figures 2, 3 and 12 of said except the loop 5 is placed on the opposite side of the main body portion 1 from the position shown in said other figures.

What is claimed is 1. The herein described new article of manufacture consisting of a wire tie comprising a main body portion having one end portion straight and the other end formed with a loop provided with an extreme end portion extending beyond and at an angle to said main body portion and the main body portion bent around said extreme end.

2. The herein described new article of manufacture.consisting of a wire tie comprising a main body portion having one end portion straightand the other end formed with a loop disposed in a plane at substantially a right angle to said main body portion and provided with an extreme end portion extending beyond and at a greater angle to said main body portion than is said loop, and the main body portion bent around said extreme end to form a second loop against the outer wall of which said extreme end portion is adapted to rest.

3. The herein described new article of manufacture consisting of a wire tie comprising a straight main body portion having one substantially straight end, and its other end having a loop located to one side of, and disposed in a plane at substantially right angles to said main body portion, said loop provided with an extreme spring end extendin from said loop to the other side ody portion and disposed in a plane making a greater angle with said body portion than said first named plane, and said body portion provided with a second loop of a larger diameter than "said tie disposed in a plane crossing said first named planes and through which said extreme spring end passes and against the outer wall of which said spring end is adapted to rest to leave a space in said second loop in which said spring end may move when pressure is brought thereon.

4. The herein described new article of manufacture consisting of a wire tie, for a package, comprising a main body portion having one end formed with .a loop, and the other end straight whereby said ties may be disposed axially of packages of different lengths with their loops in contact with one end of said packages and with their straight ends projecting beyond the other ends of said packages, and whereby a tool may be applied to said straight ends, and in all cases form knots on the latter leaving the ties under tension.

In testimony whereof I aflix my signa' ture.
